Xu Qingtong suddenly remembered that Ding Shisan had not opened the Jade Bottle at the auction either, merely giving a brief introduction to its contents. After he won the bid, the maid had also given him a Jade Slip when completing the transaction.
He took out the Jade Slip, pressed it to his forehead, and read it carefully. By the time he finished, Xu Qingtong had broken out in a cold sweat. This Ice Kite Beast Soul had belonged to a Sixth Tier Demon Beast whose strength had reached the mid-stage Golden Core.
Even with only its demon soul remaining, he might not be able to handle it. Fortunately, he had not rashly opened the bottle. Otherwise, there was truly no telling whether something might have gone wrong!
The Jade Slip sold with the Beast Soul recorded only the methods for sealing and unsealing the Jade Bottle, without explaining how to restrain the Beast Soul.
Xu Qingtong took out the Han Clan Mechanism Art and studied it again. Unfortunately, it described only how to fuse Beast Souls with Puppets, making no mention of how to seal or restrain souls.
He then took out Research on Ancient Formations and read it word by word. After reading it thoroughly from beginning to end, Xu Qingtong closed his eyes in thought. Although Research on Ancient Formations offered no direct method for restraining souls, he discovered that with slight modifications and proper application, the Blood-Soul Restriction could also restrain a Divine Soul.
Xu Qingtong shut himself in his room at the inn and devoted himself to studying the Blood-Soul Restriction. Whenever he had a new idea, he tested it.
Half a month soon passed. Having used up all his Jade Gui, Xu Qingtong had no choice but to visit the Qi Treasure Pavilion again.
